FAQ
What does MVP mean on this page?
An interactive sketch with formulas and parameters. Polished Ready labs are the full bench experience.
What does the “Friction & charge interaction” lab practice?
Tune parameters and match readouts to the “Friction & charge interaction” relations — useful for prep and demos.
Is force always along velocity?
No. Net force aligns with acceleration; velocity can point elsewhere.
How do graphs show uniform vs accelerated motion?
Uniform: constant x–t slope. Constant a: straight v–t with slope a.
